TUBULAR CARTRIDGE-SHELL.

To all whom it may concern Be it known that I, THOMAS E; MURRAY,

7 aciti'zen of the United States, residing at "New York, in the county of New York and state' of New York, have invented a certain new and useful Improvement in Tubular Cartridge-Shells, of which the following is a specification.

- The invention relates to tubular cartridge to shells for fixed ammunition, and consists in 'or depression, and in said recess there is a .central opening C for the reception of the usual rnner' or fuse. D is a reinforcin disk metal having a central ro'ection I whclli1 fits in the intheF e head B 5 .an as a centr opening registering with opening C. The circumferential edge of disk D referably overlaps the a le between the ead B and the cylindrid a l wall of theshell. After the head B and disk D 0 are ilaced in face contactythey are united by e'ectric welding, so that they become an integral mass of a strength much lgreater than the sheet metal forming the she body. This strength is still further increased by {making the reinforc' disk D of greater thickness than said s shgwn the drawing.
